The geological survey of Arkansas was begun in June 1887. 

 In that month I discovered some of the bauxite beds of Pulaski 

 county, but the nature of these deposits was not announced 

 until January 1891, when I gave a short account of their distri- 

 bution and character.^ 



The many inquiries concerning the Arkansas bauxites, both 

 from geologists and manufacturers, furnish sufficient reason for 

 the present more extended account of them. This is made still 

 more necessary by the fact that my report on the clays, kaolins, 

 and bauxites of Arkansas has not yet been published, and it 

 seems improbable that it ever will be published by that state. 



In view of the fact that Owen was State Geologist of Arkan- 

 sas from 1857 to i860, and that other surve3^s were carried on 



'This is also sometimes written beauxite. The word is derived from Les Baux or 

 Les Beaux, the name of a town in the south of France. Pronounced bozile, not 

 bawksite. 



^ K letter on this subject was addressed to Governor James P. Eagle and was 

 printed in the Arkansas Gazette and the Arkansas Democrat of January 8, 1891, and 

 reproduced in the Arkansas Press in several numbers from January 18, 1891, until 

 1893, and also in the third and fourth biennial reports of the Commissioner of Mines, 

 etc., of the state of Arkansas. A brief notice of the deposits was also published in 

 the American Geologist iox y\.'A.xc\\ 1891, pp. 181-183.
